[0012] Furthermore, the fixing mechanism also includes an installation groove, which is opened on the lower surface of the lower pressure plate near the center end of the test shell, and a flexible clamping mechanism is provided inside the installation groove to facilitate the installation of the flexible clamping mechanism.

[0013] Furthermore, the flexible clamping mechanism includes a top plate and a rubber pad. The top plates are slidably connected to the inner wall of the mounting groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the vehicle new energy battery detection device has the following advantages: 1. According to the size of the battery, the staff adjusts the position of the slider and pushes the slider outward or inward so that the slider slides along the outer surface of the limit column on the inner wall of the slide groove, and compresses spring 1 at the same time until the slider moves to a position that can adapt to the battery size, and can provide appropriate reverse force through the action of spring 1 to ensure that the battery is firmly fixed in the center of the test shell. Then the staff holds the screw and uses the pin in the L-shaped groove as the center through the fixed block so that the screw can rotate at a certain angle so that it remains parallel to the side of the battery. The staff holds the lower pressure plate and starts to rotate the internal threaded ring at the same time. The threaded connection between the internal threaded ring and the screw causes the internal threaded ring to move downward along the axis of the screw.

[0017] 2. When the lower pressure plate contacts the upper surface of the battery, the rubber pad on the top plate contacts the upper surface of the battery synchronously and generates a certain extrusion force. The extrusion force drives the top plate to move upward along the inner wall of the mounting groove and moves along the sliding hole on the lower pressure plate through the sliding column. At the same time, the compression spring 2 provides an elastic buffer for the rise of the top plate. At the same time, the rise of the top plate drives the connecting rod 1 and the connecting rod 2 to rotate around the pin shaft on the U-shaped seat. The rotation of the connecting rod 1 and the connecting rod 2 drives the guide block to slide and avoid in the guide slide groove, so that the top plate can not only rise and fall in the mounting groove, but also maintain appropriate contact with the surface of the new energy battery of the vehicle during movement, thereby effectively realizing the function of flexible clamping, avoiding battery damage caused by excessive extrusion, extending the service life of the battery and ensuring safety during the test.

The second spring 106 is sleeved on the outer surface of the slide post 105. According to the size of the battery 14, the staff adjusts the position of the slider 904 and pushes the slider 904 outward or inward.The slider 904 is made to slide along the inner wall of the slide groove 903 along the outer surface of the limit column 901, and the spring 1 902 is compressed at the same time until the slider 904 moves to a position that can adapt to the size of the battery 14, and the appropriate reverse force can be provided by the force of the spring 1 902 to ensure that the battery 14 is firmly fixed in the center of the test housing 1. Then the staff holds the screw rod 907 and uses the fixing block 906 with the pin in the L-shaped groove 905 as the center to allow the screw rod 907 to rotate at a certain angle so that it remains parallel to the side of the battery 14, which can effectively fix automobile new energy batteries of different shapes in the test housing 1. When the adjustment is completed, the staff holds the pressing plate 910 with their hands. , and at the same time, the internal thread ring 908 begins to rotate. The threaded connection between the internal thread ring 908 and the screw rod 907 causes the internal thread ring 908 to move downward along the axis of the screw rod 907. As the internal thread ring 908 moves downward, it gradually pushes the lower pressure plate 910 to move downward. This process is gradual, so that the lower pressure plate 910 gradually approaches the upper surface of the battery 14. When the lower pressure plate 910 contacts the upper surface of the battery 14, the rubber pad 102 on the top plate 101 contacts the upper surface of the battery 14 synchronously and generates a certain extrusion force.

Battery 14 is placed at the center of the bottom wall of test housing 1. Battery 14 is located inside fixing mechanism 9. It also includes sealing groove 11. Sealing groove 11 is opened on the upper surface of test housing 1.

The cover 6 is separated from the sealing groove 11 by the handle 4, and then the battery 14 is placed in the center of the bottom wall of the test housing 1. The cover 6 is then clamped with the sealing groove 11 to facilitate sealing during the test process. The exhaust pipe 2 is also included. The exhaust pipe 2 is fixedly connected to the exhaust hole at the front end of the upper surface of the transparent glass 5. The top of the exhaust pipe 2 is provided with an air valve 3. During the high-temperature test process, the air valve 3 on the exhaust pipe 2 can discharge excess gas from the interior of the test housing 1, thereby effectively controlling the gas pressure inside the test housing 1 and preventing the problem of excessive pressure caused by heating; Interlayer 12: It is opened on the inner wall of the test housing 1. An electric heating wire 13 is provided inside the interlayer 12. The operation of the electric heating wire 13 is controlled by the single-chip microcomputer 8 to heat the interior of the test housing 1 to simulate the working state of the new energy vehicle battery in a high temperature environment; Temperature sensor 7: It is arranged on the right side of the test housing 1. The detection probe of the temperature sensor 7 extends into the interior of the test housing 1. The temperature sensor 7 detects the internal temperature of the test housing 1 in real time, and can observe the state of the battery 14 at high temperature through the transparent glass 5 on the cover 6. The detected data is transmitted to the single-chip computer 8; Among them: it also includes a single-chip microcomputer 8, which is arranged at the lower end of the right side of the test shell 1, the input end of the single-chip microcomputer 8 is electrically connected to the external power supply, the output end of the single-chip microcomputer 8 is electrically connected to the input end of the electric heating wire 13, and the single-chip microcomputer 8 is bidirectionally electrically connected to the temperature sensor 7.

[0022] The working principle of the automobile new energy battery detection device provided by the present invention is as follows: first, the cover 6 is separated from the sealing groove 11 by the handle 4, and then the battery 14 is placed in the center of the bottom wall of the test shell 1. Then, according to the size of the battery 14, the staff adjusts the position of the slider 904 and pushes the slider 904 outward or inward to make the slider 904 slide along the inner wall of the slide groove 903 along the outer surface of the limit column 901, and at the same time compresses the spring 1 902 until the slider 904 moves to a position that can adapt to the size of the battery 14, and can provide an appropriate reverse force through the action of the spring 1 902 to ensure that the battery 14 is firmly fixed in the center of the test shell 1. Then the staff holds the screw 907 and fixes it through the screw 907. The fixed block 906 takes the pin in the L-shaped groove 905 as the center, so that the screw rod 907 can be rotated at a certain angle, so that it remains parallel to the side of the battery 14, which can effectively fix automobile new energy batteries of different shapes in the test shell 1. When the adjustment is completed, the staff holds the lower pressure plate 910 by hand and starts to rotate the internal thread ring 908 at the same time. The threaded connection between the internal thread ring 908 and the screw rod 907 causes the internal thread ring 908 to move downward along the axis of the screw rod 907. As the internal thread ring 908 moves downward, it gradually pushes the lower pressure plate 910 to move downward. This process is gradual, so that the lower pressure plate 910 gradually approaches the upper surface of the battery 14. When the lower pressure plate 910 contacts the upper surface of the battery 14, the top plate 101 The rubber pad 102 is in contact with the upper surface of the battery 14 at the same time, and generates a certain extrusion force. The extrusion force drives the top plate 101 to move upward along the inner wall of the mounting groove 911, and moves along the sliding hole on the lower pressure plate 910 through the sliding column 105, while compressing the spring 2 106 to provide an elastic buffer for the rise of the top plate 101. At the same time, the rise of the top plate 101 drives the connecting rod 104 and the connecting rod 2 108 to rotate around the pin shaft on the U-shaped seat 109. The rotation of the connecting rod 104 and the connecting rod 2 108 drives the guide block 103 to slide and avoid in the guide groove 107, so that the top plate 101 can not only rise and fall in the mounting groove 911, but also maintain contact with the surface of the new energy battery of the vehicle during the movement. Appropriate contact is made, thereby effectively realizing the function of flexible clamping, and then the cover 6 is snapped into place with the sealing groove 11 to facilitate the sealing during the test process. At the same time, the electric heating wire 13 is controlled by the single-chip microcomputer 8 to heat the inside of the test shell 1 to simulate the working state of the new energy battery of the car in a high temperature environment, and the temperature inside the test shell 1 is detected in real time by the temperature sensor 7. The state of the battery 14 at high temperature can be observed through the transparent glass 5 on the cover 6, and the detected data is transmitted to the single-chip microcomputer 8. After receiving the data, the single-chip microcomputer 8 analyzes, processes and integrates it, and transmits the integrated data to the external display, so that the staff can conveniently observe the state changes of the new energy battery of the car at different temperatures.And evaluate its performance in a high temperature environment. During the high temperature test process, the excess gas can be discharged from the inside of the test housing 1 through the gas valve 3 on the exhaust pipe 2, thereby effectively controlling the gas pressure inside the test housing 1 and preventing the problem of excessive pressure caused by heating.

[0023] It is worth noting that the specific model of the single chip microcomputer 8 disclosed in the above embodiment is STM32F207VCT6, the temperature sensor 7 is recommended to use C15-M53R, and the electric heating wire 13 can be selected from Ocr21al6nb. The single chip microcomputer 8 controls the operation of the temperature sensor 7 and the electric heating wire 13 using methods commonly used in the prior art.
